Syntax
TableModify(<Table control> , <Row> [, <Index>])
<Table control>: Control name
Name of the control to be used. This control can correspond to:
  • a Table control.

  • WINDEV a Combo Box control with table.
If this parameter corresponds to an empty string (""), the control used will be the control to which the current event belongs.
<Row>: Character string
Modified row replacing the specified row. This row has the following format:
<Element of column 1> + TAB + <Element of column 2> + TAB + ...
<Index>: Optional integer
Index of the row to be modified. The value of first row is set to 1.
Index not specified or equal to -1The current row is modified. This constant has no effect if no row is selected.
Index greater than the number of control rowsA WLanguage error occurs.

Use conditions

TableModify can be used on:
  • a Table or TreeView Table control based on a data file.
  • a Table or TreeView Table control populated programmatically.
  • a single-selection or multi-selection control.
    WEBDEV - Server codePHP Reminder: Multiselection is not available for classic Table controls.
WEBDEV - Server codePHP This function is available for Table controls in "Server" and "Server + AJAX" mode, and for TreeView Table controls.
WEBDEV - Browser code This function is available for Table controls in "Browser" mode only.
WEBDEV - Browser codeAndroidiPhone/iPad The TreeView Table control is not available.
WEBDEV - Browser code The TreeView Table control is not available.
AndroidiPhone/iPad Table controls based on a data file are not available in edit mode. TableModify cannot be used on Table controls based on a data file.

Row characteristics

  • Each row element is changed into the type of the associated column.
  • If one of the elements corresponds to an empty string ("") or to 0 (depending on the column type), its value will be overwritten.
    For example:
    TableModify(TABLE_CustomerTable, "Moore" + TAB + "Peter" + TAB + "" + ...
    TAB + "06/21/72")
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets.
    For example:
    TableModify(TABLE_CalcTable, (53+29) + TAB + (83-21))
  • To modify the value of an element in a row, use the following syntax:
    TableName.ColumnName[RowIndex] = NewValue

Table or TreeView Table control based on a data file: Modifications in the linked data file

If the cascading input is enabled, the data file linked to the control is automatically modified when the user goes to the next row.
If the cascading input is not enabled, the data file linked to the control is not modified. To write the record into the linked data file, TableSave must be called after TableModify.
Remarks:
  • The "Cascading input" option can be selected in the "Details" tab of the control description window.
  • Java The cascading input is not available for Table controls with direct access to the data source. This option is only available for Table controls populated programmatically and with in-memory data source.
  • Versions 19 and later
    WEBDEV - Server code Cascading input is only available for "Server + AJAX" Table controls based on a data file.
    New in version 19
    WEBDEV - Server code Cascading input is only available for "Server + AJAX" Table controls based on a data file.

Modifying a record in a Table control based on a data file and releasing a Trigger

You have the ability to activate a trigger when modifying a record in a Table control based on a data file. For more details, see the documentation about HDescribeTrigger.

TableModify function and Modified property

TableModify has no influence on the Modified property. The Modified property is used to know if the current row has been directly modified by the user (direct input in the control).
